Abstract In superionic crystals, liquid‐like ionic diffusivities often come hand‐in‐hand with ultra‐low thermal conductivity and soft vibrational dynamics. However, generalized relationships between ion transport dynamics remain elusive due to the diversity of materials complex underlying mechanisms. Here, links in close‐packed lithium halide conductor Li 3 YCl 6 (LYC) are examined using a suite atomistic first‐principles methods. It is shown that configurational disorder, lattice...
Hybrid lead halide perovskite semiconductors (LHPs) are recently reinvigorated class of materials with impressive performance in optoelectronic devices. Unlike the “classical” Si or GaAs, LHPs properties governed by structural fluctuations within seemingly well-defined high-temperature cubic phase. Recent work has uncovered potential short-range order arising from these fluctuations. However, origin and structure this unresolved, impeding our understanding technologically relevant including...
Surprisingly, a few seconds–minutes of compression at room temperature can increase the rate dynamic bond exchange as measured by better self-healing, even for thermoresponsive bonds which do not under ambient conditions.
Abstract Dynamically cross‐linked polymer networks have attracted significant interest in recent years due to their unique and improved properties including increased toughness, malleability, shape memory, self‐healing. Here, a computational study on the mechanical behavior of dynamically is presented. Coarse grained models for different network configurations are established using molecular dynamics (MD) simulations predicted. Consistent with experimental measurements, simulation results...
Hybrid lead halide perovskites (LHPs) are a class of semiconductor with novel properties that distinctively governed by structural fluctuations. Diffraction experiments sensitive to average, long-range order reveal cubic structure in the device-relevant, high-temperature phase. Local probes find additional short-range lower symmetry may govern structure-function relationships LHPs. However, dimensionality, participating atoms, and dynamics this unresolved, impeding our understanding...
